Japanese Last Name

Hey everyone,

I am half American and half Japanese. I have a western last name. I also do not look Japanese despite my ancestry. When living in Japan, will it be easier for me to use my Japanese last name? It is a common last name and I’m curious if it’d help me in everyday life from banking, apartments, job interviews, etc.

TLDR: Will using my Japanese last name, despite not looking Japanese, make my life “easier” in Japan?

Thanks everyone and if any other hafu or foreigners in general have this experience I’d be thankful to hear it.
